CONVERTIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 582,603, dated May 11, 1897.

Application filed April 2 9, 18 9 6.

To all whom it may concern.-

Be it known that I, LEMUEL A. CHICHESTER, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Convertible Chairs, of which the following is a specification.

My invention is an improvement in that class of convertible chairs for which I have obtained various Letters Patent of the United Statesas, for example, Letters Patent No. 517,946, dated April 10, 1894.

The essential features of my present improvement are hereinafter fully set forth, to gether with the advantages that may be naturally attributable thereto, and illustrated in the accompanying drawings, wherein-- FigureI represents a side view of a chair embodying my invention in one of its convertible positions. Fig. II represents a like view thereof in the other of its positions. Fig. III represents a rear view thereof in position corresponding to Fig. II. Fig. IV represents a vertical section of a portion of the chair-seat and the handle-bar with concomitant locking parts. Fig. V represents a side view of the locking-latch detached. Fig. VI represents a side view, and Fig. VII a like view, of coacting hooks for retaining the parts in the position shown in Fig. II.

The letter A indicates the chair-seat, B the back, and 0 arms connecting the seat and back in the usual way.

D indicates side sills or beams which support the seat A and which also form the bearings for the axles e of wheels F, which constitute the support for the chair when it is used as a trundle or perambulator, as shown in Fig. II.

The leg-frame is composed of a main part or section G (each of its members being marked with that letter) and of an auxiliary section H, having a cross-bar H, which con-' stitutes a handle, this last-named section II II being pivoted to a member of the section G, as at z, and being convertible from a handle into a leg-frame, or vice versa.

The cross or handle bar H of the convertible frame is provided with a socket in, (see Fig. IV,) which opens in a direction toward Serial No. 589,525- (No model.)

the interior of the chair, and ata point near the rear part of the chair-seat A the latter has a hook l, which projects in a direction downwardly and rearwardly therefrom, while to rear edge of the cl1air-seat is pivoted a swinging latch 'm. The arrangement of these parts 70 Z on is such that when the convertible frame H is adjusted to the position shown in Fig. I the socket is and hook Z are brought into engagement with each other, and if the latch m is then adjusted to its locking position, as shown in Fig. IV, the handle-bar is thereby effectually retained in its position of engagement with said hook, while if'the latch is adjusted to a lateral position to clear the handle-bar the latter may be readily displaced for bringing the frame and other parts to the position shown in Fig. II.

The side sills D are formed of a semielastic or springy material, preferably of wood, which is bent into a U shape, and one arm of each of the sills forms the support for the chairseat A, while the other arm thereof forms the bearing for the chair-wheel axles. The side sills also form a support for the forward side portion of the leg-frame G, which portions of said frame are mounted on the forward wheelaxle. This forward wheel-axle is composed of a rod 6', which extends through the side sills D, as well as through the proper side portions of the leg-frame G, and is secured to the leg-frame, as by means of a head at one end of the rod and a nut at the other end thereof, this red thus constituting a screwbolt for permitting easy and effective adj ustment of the parts to which it appertains.

The hooks 0 0 (shown in Figs. VI andVII) are intended to lock the parts in the position shown in Fig. II, and the swinging frame (shown at J) is intended to act as a foot-rest for the occupant of the chair.

If desirable, the chair-back B may be extended downwardly below the seat A and joined to the rear ends of the side sills D, as shown in Fig. I in dotted lines, and in that event the side sills may be composed of a rigid or non-elastic material.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

In a convertible chair of the character specified, the convertible handle-frame and leg-frame having its handle-bar provided die-bar in engagement with said hook, subwith a socket opening toward the interior of stantially as shown and described. the chair, a hook at the rear of the chair-seat m projecting downwardly and rearwardly there- LEMUEL (HUGHES 1 5 from for engaging with the said socket of the \Vitnesses:
